Kolam at 47th and Memorial has changed hands and is now Himalaya. The interior has been slightly improved and the buffet table is now on the wall at the left of the restaurant instead of at the back. Tulsa is very weak on Indian/Pakistani food and most places are at best OK. The main thing about Himalaya's buffet is it now has about twice as many dishes as Kolam used to have and also has a variety of meats instead of just chicken. Quality is about the same - maybe slightly better. If I have the energy (which I usually don't) I can cook better myself - but if I need an Indian fix this is probably the best buffet in town.
