There is seating near the fish and chips stand in UK, as well.
We usually eat whatever we want and just plant ourselves along the fence line, bench or not.
My fave eats in WS are Tangerine Cafe in Morocco and the bakery in France.
Even if we do a table service that night, we hit the bakery for yummy desserts to eat while waiting. Be aware - the line there gets long the closer it gets to IllumiNations. Last time we stood for 30 minutes waiting and almost missed the show.
