Mama's Pretzel Kitchen is a good walk from the front gates of SeaWorld, Orlando. Tucked away in the "Sea of Fun" area of the park (or just "above" Shamu Stadium if you are looking at a SeaWorld map), the tiny pass-through shop actually has some really good eats. You can't go wrong with beer and pretzels in a theme park, and Mama's Pretzel Kitchen takes that up a notch by offering pretzels stuffed with... stuff.
As with most Sea World locations, there's not much indoor seating around (if any) but there are quite a few umbrella covered tables. If you walk around the area a bit, you might find an unassuming "coffee and soft serve ice cream shop" that has fully covered open air seating (which would be to the left of the Pretzel Kitchen, when looking directly at the building).
As far as crowds go, if the place it packed… it's probably because one of the nearby shows just let out. Give it 15 minutes and the lines will be much shorter. One of the best times to visit Mama's Pretzel Kitchen is while a show is going on at the nearby Shamu Stadium!
