Not sure why all the negative reviews! I recently visited for the first time and was pleasantly surprised.
You can purchase "one bowl" or "unlimited". Unlimited is a far better value for the money (as you could probably guess). While there are helpful signs to give you suggestions on what to create, it was more fun to mix and match unique combinations!
As a vegetarian, I thought there was a fabulous selection of veggies, and even tofu. What a fun experience!
