Yesterday I visited Aqui Cal Mex restaurant in Cupertino. I liked the place and the menu and hence this recommendation. They have a prominent Vegetarian section in the menu. Its supposed to be a California Mexico Fusion restaurant.
You need to order at the counter and there are no waiters to take your order at your table. But they have lots of seating and a nice place to sit and chat with friends.
Thanks to Bhavini for originally recommending it to me. Here is the address:
Aqui Cal Mex : 10630 S De Anza Blvd, Cupertino, CA 95014
Wait.. we were there too.
