Thumbs up for India Sweets and Spices on Los Feliz (there are several different locations, apparently owned or managed differently). I'm a strict vegan and they are able to accomodate my diet. They have substantial dairy but otherwise they are 100% vegetarian. They are a counter-service eatery...no table service...you order at the counter after you study the various food options of the day that are pre-made through a display case window. ASK if they have dairy in their foods...some do, some don't and make sure you identify Ghee (clarified butter) in your objection. When I order their Masala Dosa (my favorite dish there), I specifically ask that they use oil and not ghee. The owner is such an incredibly friendly fellow, that he is part of the joy of eating there. He is always happy and greets me every visit. The atmosphere is a bit barren and cold, but I love the Bollywood videos that they have playing on a tv there. There is a large indian foods market attached...this is where I buy my Vicco toothpaste (the only toothpaste that I've found that doesn't contain glycerin, which blocks the beneficial recalcification of tooth enamel from our saliva), my indian spices, and all types of unique rices and amazing food ingredients that I still don't know how to cook with.
Cons: counter-service, barren atmosphere, have dairy
