Ignore this advice. The Vindaloo is typically the hottest thing on the menu. Masala and tandoori are your best bets. Saag is ok too, spinach and cheese, not spicy. Samosas are nice appetizers. I like naan bread (leavened and oven baked) more than chapatti (like a tortilla) or pappadom (crisp flatbread.)
Get a Mango Lassi if you have “hot” issues, the milk fats will dilute the capsaicin & alkali in the curry.
Have it with a lager and again Red Dwarf's Dave Lister would want it that way!
