Firstly, I loooooooooooooooooooove Indian food.
Secondly, Indian food, at least not as served in the US, does not contain very many “exotic” ingredients, other than spices you may not be used to. They use non-scary meats - chicken, lamb, pork, some serve beef.
The meatless dishes may have some unfamiliar ingredients, but nothing scarier than paneer - which is a firm cheese.
They will usually be willing to reduce the spiciness of dishes if asked. The only spiciness problem I’ve ever run into is them not believing me when I say I really do want my Vindaloo “very spicy.”
If you’ve never had Indian food before, and don’t like too spicy, try Tandoori Chicken.
It is non-threatening. Of course, compared to other Indian food, I find it downright boring, but I don’t hold that against the folks for whom it is their favorite Indian dish!
Some of my favorites, when I first started eating Indian food:
Papadum - some restuarnts bring these out to start you off, without having to be asked. They are crispy wafers with spices in them - but not actually HOT. They are so yummy. I like the ones that are heavy on the black pepper and cumin.
Samosas - these are deep-fried triangular turnovers. Can have meat in them, but I like the potato and pea ones mysels. If they bring you the trio of condimenst (one bright orange and chunky, one dark and purple-y, one green) use the purple one to dip the samosas - it is tamarind sauce and is fruity and yummy. Mmmm.
CAUTION: If you don’t like spicy - do not even touch the orange-red lumpy condiment - it is onion chutney with tons of hot pepper. I love it on naan, but it is not for the faint-of-sewat-glands. Or if you want to kiss anyone later.
Chicken Korma, or anything “korma” is usually not too spicy. It is a cream-based sauce, slightly sweet, with nuts and sometimes raisins.
Try also some of the breads, naan and poori are both wonderful. If they onion or garlic naan, that’s a good way to get a feel for the flavors of Indian food without risking too much spice.
If you like spinach, try anything “saag.” Yum yum yum, and not very spicy.
I looked to see if I could find a web page for them, so I could ook at their emnu, but a quick search didn’t turn one up.
Hope this helps.
