What a shame you had this experience. Ive been here lots of times and while its true that your options are limited, they can and will adjust the menu for you by doing an open salad sandwich or a breakfast with some changes such as beans for eggs etc.they also do lots of juices. The menu is very limited anyway but with a but of gentle negotiation, they will help. Like many places, i guess-you have to be prepared to assust them in understanding what youd like. I could only suggest the waiter was a bit off that day as normally theyre really good, but you have to be willing to work with them as its not a vegan restaurant (no restaurant in the area is vegan). Juices and very simple meals are easy here, but its the location and atmosphere that makes it a nice place.
