Orlando MUST Eats
There is a really great all veg Indian restaurant on orange blossom trail near oakridge, it's called Bombay but just look for the sign that says House of Spices. I've heard some good things about Loving Hut which is near the Vietnamese district on 50, also all vegetarian. Ethos, on Orange Ave, is another example but it's not ethnic, I hear their meatless Philly is great though! Sorry I don't have any great suggestions for the convention center side of town where you'll be staying, will think on it though and get back to you.
