Eaten at Thai Pepper a few times.. the thing is it's usually sufficient in that it's fresh dishes are good portions. The drawback for me is that the flavors are not balanced and sometimes the crispness of items like the tempura shrimp are soggy, and still served hot? It's confusing for sure. I've also noticed that the spice level isn't consistent. Mild is really spicy, medium is really really spicy.. and I'm afraid to try "hot". This is from a guy that loves pretty spicy food.
My least favorite item that I thought I would love was the ginger chicken. Really spicy.. but otherwise bland and not a whole lot of chicken. Lots of veggies, which is nice.. but not allot of meat.
I've been a fan of their wonton soup however, and the crispy veggie eggrolls are good. Overall, I would prefer the fusion style Thai of places like LeThai on east Fremont.
Happy Eating too you!
