You can put in a special request and get Vegan dishes. It's not an easy request, so a days notice would be great. (I'm assuming you mean a strict Vegan dish, right?) My sister did that for years, and she was VERY strict with hers.
No problem, but like I said, a days notice would be the best thing. You can call Chap directly, that would be your best bet, and he can go ahead and take your order!
