Indian Restaurants near Bethany Beach?
I'll start by saying that you are a woman after my own heart, I love Indian food. That being said, I think your choices are more than slim in the beach area. I have tons of luck with Aarti Sequeria's recipes from her show Aarti Party. She does a fusion of Indian and more accessible ingredients and I have loved everything I've made.
I have good luck at Williams and Sonoma. They make some jarred sauces ( tikka masala, etc.) that taste very good. I was surprised by the quality. I also buy grocery store naan and brush with olive oil and grill. I hope that these suggestions help you.
If you ever wind up in the Wilmington area there is a hole in the wall Indian place called India Palace on Maryland Avenue that is excellent. I rant and rave about it all the time on CH.
