A side order of cole slaw doesn't count. What Isn't Listed Certain classes of restaurants almost always have some few dishes that are appropriate, so I'm not going to list an individual place unless they seem to have gone out of their way to provide for vegetarians, or unless I feel like it. Otherwise this would turn into a regular list of Houston restaurants, which is being done by other people already. Italian restaurants usually have a tomato or mushroom sauce that doesn't have meat in it. Some pizza restaurants use sauce and crusts that are vegetarian or vegan.
Most Chinese restaurants have a few vegetarian dishes.
Most Thai restaurants have a few vegetarian dishes. Most Indian restaurants have a lot of vegetarian dishes, usually heavy on the dairy products. People always suggest that Mexican or Tex-Mex restaurants must be great, what with all the rice and beans and things. Sometimes this is true, and if you eat dairy you can usually get a cheese enchilada. All too often, though, beans are made with lard, and rice with beef or chicken stock.
