I've had some outstanding Indian cuisine in Providence, Boston, Detroit, Cleveland, Akron, and Chicago. This food is authentic but average at best. I usually get chicken with my curry. My favorite is Vindaloo but I tried it at Nawab on two different occasions and was left feeling dissatisfied. Since then I've opted for the Mahkani, Saag, or Tikka Masala. I like it hot, but have to ask for Indian hot to experience any serious heat, which is atypical for an Indian restaurant. I did recently sample the lamb Vindaloo, Indian hot, and it was decent, so I may give the Vindaloo another chance. I almost didn't return after my first time because the basmati rice was hard as a rock, which was presumably a one off occurrence as it hasn't happened again, but it certainly didn't leave a good first impression. The Naan is usually ok but occasionally it is extremely greasy. The vegetable Samosa is average. The prices are a little high but in line with most other Indian restaurants. The atmosphere is poor and likely the main reason this restaurant has never had more than a few guests at a time, at least everytime I've been there. The interior is clean but the decor is dated. The exterior isn't very appealing either. The music is being played through a blown speaker. Nawab should invest in a new sound system. It sounds awful. I must say the service is very good. The wait staff is definitely attentive but not intrusive. The beer selection isn't bad. Expect to find Indian staple beers Taj Mahal and King Fisher, of course. It's definitely worth trying for yourself, at least once, especially since it's the only choice for Indian food in the tri-state area.
