I can cook better at home. – Decided to come to KO Prime for a nice dinner outing with my husband and was truly disappointed. The ambiance is nice, service was good, but the food was definitely mediocre. We ordered the Veal sweetbread which was quite tasty and a good start to the meal, so we were looking forward to our entrees. We ordered the pork special, braised short ribs, and side of mac n cheese. The pork was bland and tasteless, the short ribs were nice and tender, but also had no flavor or taste to it, and I can get better mac n cheese at KFC and Boston Market. That's not saying much since those are known chains. If you want a good mac n cheese, go to John Harvard's.

Looking at the tables around us, everyone was happy with their orders and had ordered similar food. I suppose our taste buds aren't refined enough to appreciate the fine essences they cook with.

PRO to our experience: the mini appetizer and soup that were a special compliment of the chef that day. Apparently they share these mini surprises with all their guests. Those were nice and tasty. We just wish we could say the same for our entrees. We won't be going back there.

CONS: Overpriced entrees that had no flavor.

Solid prime rib – I went here with a bunch of friends to try the all-you-can-eat prime rib special. For $30, you can order as much prime rib as you want. From the outset, we told our server that we wanted the prime rib to keep coming. He promised us that he would take care of us, which he did for the most part. The prime rib itself is cut into small slices. So when you are finished with your first (after a couple of minutes), you will have to wait sometime to get another order. This can be annoying if you have somewhere to go after dinner or if you are really hungry. The prime rib is very good though. It's cooked medium-rare (very bloody) with a lot of au jus. I didn't try anything else on the menu, but this restaurant seemed to be pretty solid.

Overpriced – Restaurant week review: Like many places for restaurant week you just don't get a quality meal anymore. We ordered the steak frites (not restaurant week menu) and cod from the restuarant week menu. Both were fine, nothing special. The service was average at best. For the price, there are finer restuarants to visit.

Best New Reastaurant in Town! – KO Prime has done everything right! Great food and great service. Chef Jamie Bissonnette's take on a new high end steak house is fantastic. The steaks were cooked perfectly, the short rib mac and cheese is to die for and the mushrooms are the best in the city! Good thing i didn't listen to any of the reviews below, obviously they were done by people that either never eat out, never worked in a restaurant on have no taste buds.

Huge Disappointment!!! – Never been more disappointed at a so called "high end" steak house. Sure, the place was pricey but we all new that and expected to get what we pay for. But boy, were we wrong. Went with a party of five to celebrate a birthday and none of us were impressed. Steak was dry and overcooked and when the waiter was informed, they brought out a little flashlight and hunched over my shoulder to examine it at our table...how LOW CLASS!! I mean I felt like I was getting a PAP smear at the table!! All the apetizers and side dishes were nothing fantastic, not to mention our rissotto was RAW with crunchy rice grain....Our lobster was also overcooked (tough and chewy). I mean, come on, does Mr. Ken Oringer have any clues what's going on at this place? I can't imagine he does, he should be EMBARASSED to have his name associated with this place!!

Outstanding steak house, food lives up to its rep – My husband took me there for my birthday and we had an absolutely fantastic meal! The room is beautiful and cosey with a mix of booths and tables. Knowing it was my birthday, the chef sent us out a few dishes on him... nice to know that someone paid attention when my husband told them it was my birthday! All the food was amazing and cooked to perfection... the one dish that I just cannot get out of my mind was this homemade sausage that had this french farmer's cheese melted inside of it... unbeleiveable! Have never had anything that tasted so incredible. Really good time.

Everything and More – If I followed all the negative and "it was OK..But....." reviews I have read and listened to about Ken Oringers latest venture, I and my partner would have missed out on what we both agreed was as near a perfect evening as one could have in a restaurant. From the moment we walked up the marbled stairs and were greeted by a most genuinely warm hostess, to the moment we savored the last sip of a most stupendous wine, the evening was flawless.

The bone in rib eye I had was cooked to perfection and the side if chantarelle mushrooms only added to the near decadance of the entree. The size of the portion was extremely generous only to be matched by the exquisite flavor. My companion had the king salmon which was moist and cooked with just the right amount of enhancing spice.

I could go on and on in great detail about the surroundings, the service, etc......but that I feel would detract from your own unique experience. I would like to thank all those before me who said they had a sub par experience for my initial apprehention, I feel only helped project our experience out into the stratosphere.

Expensive .... it can be, depending upon how much you wish to induldge.. that is relavant only to the individual. My bottom line ................. GO .......... Often.

Waste of time and money – My fiance and I went for dinner this past Saturday. We often go to Ruth's Chris or Mortons when we're in the mood for a good steak, but we decided to give this place a try. Unfortunately it was a bad decision. After being seated we asked the hostess to see the wine selections. When the waiter came over he handed me the menu and said "wines by the glass are on the first page......but they are a bit on the pricey side". I thought this was a very interesting comment, seeing as we were just about to spend over $300 on a dinner for two, not including a 20% tip, without batting an eye..... In my opinion, its not usually in your best interest as a waiter to offend your patrons before they've even spoken a word to you!... Moving on, the both of us decided on the filet, and ordered them medium rare and medium. Both filets came out medium well and to our surprise were saturated in a ridiculously salty marinade of what tasted like teriyaki sauce. The tast actually can be compared to bad homemade steak tips from someones backyard barbeque . They were sooooo salty and saturated that I had to swish water after every bite. I know that most restaurants will use salt and pepper or additional rubs but this was over the top. We ate only about a quarter of the steaks and finished off our apparently "too expensive" bottle of noir and asked for the check. The steak should be in no way compared to any of the top steakhouses in Boston (Ruth's Chris, Mortons, Grill23, Abe & Louies). We will not be returning.

Just Pass On KO Prime – Just arrived home from ko prime. It was easy to get a reservation. Should have known right there. The host was helpful and the valet was great. The service was not good. After we had our meals, c+ at best, we received the check. I noticed the glass of wine my wife has was 20$ dollars. Don't mind spending money when the food is great and the service is equal(neither) but the response from our waitress was disappointing. She showed my wife the menu and said "it's right here hun!" Wrong answer. We eat at other fine restaurants in the city, this is never going to be one again. Just Pass On This One!!!

Waste of Time and Money – The wine list was quite nice, so if all you are interested in is wine, go for it. Although be careful, the wine we ordered was not the one served (they brought out the 2nd wine of the St. Estephe we ordered). The fois gras was excellent, by far the best appetizer offered from the "Hot" section. The service was appalling. The entrees were brought out sequentially, misplaced on the table, and two of the three had to be sent back because they were not cooked properly (med-well was a cool-pink center). When they were returned to the table, the sides which had been on the plate had been placed in the broiler with the steak, indicating they just threw the plate back in the oven, and overcooked the braised chard. The duck came back over seasoned.

The wait staff disappeared after taking the dinner order

I would not go here again, ever, under any circumstances. Take the money and go to Denny's instead.
