Yummy Sushi has a la carte sushi and all you can eat. We had all you can eat sushi lunch for 2 ($15.99 each) on a weekend.
They have an extensive menu - there are lots of choices (and lots of typo's!). The rolls were decent in terms of filling to sushi, and I was glad that they weren't filled with excessive amounts of cucumbers (particularly for the eel roll which came with avocado instead). Presentation was meh for the rolls, but the salmon roses were decently well done for an AYCE place.
The BBQ beef ribs and the deep fried cheese wonton were good. I was surprised that they brought out the avocado salad so late after a number of kitchen and rolls had arrived (normally these come out first thing).
Good dessert options - ice cream in 5 flavours, mango pudding, strawberry jelly and deep fried banana.
I was annoyed at the number of flies that were flying around our table near the preparation area. And I think I killed a mosquito. Service was good and quick, but it wasn't that busy when we came to begin with. They gave us a beef fried rice that we didn't order, but they took it back without complaint - I like how they give you back a copy of the original order sheet.
They take credit card, but they don't take tap, so no Android Pay. :(
