When I am ill, I like to eat soup, spicy food or dishes with turmeric. Here are some of the places I go. But you don't have to wait to be sick to try any of these dishes.
A small house that looks like a dinner inside, ignore the gruffness & enjoy great soups (my fav is duck) & other well prepared Vietnamese fare.
Solid inexpensive vegetarian food, Try the thali, marsala dosa or cheese uttapum for a meal or one of the chats for a snack.
Family run Tex-Mex place with all the classics. Start with Jose's dip a Molina's classic.
Beef noodle soup & pan fried dumplings are spectacular. The bao is pretty special & side dishes in the frig are worth more than a glance. Bonus everything is made in-house & prices are low.
