Went last night based on the write up in the Weekly Yelp and I am definitely a fan! For $35, including a big tip, the two of us ate like royalty. We had: Hopper Combo #2, plain rotis (2), pitthu combo with the mutton curry (soooo good), and a vegetarian lampries.
Sure it's not a fancy location or atmosphere, but the food is so good and so inexpensive that absolutely outweighs the lack of ambiance. It's not an "impress the boss/in-laws" kind of place. It's a "i love tasty food" place.
For cheap and cheerful and amazingly tasty, you can't beat the Hopper Hut.
