Scott,
I don’t regularly watch football games, but I know expats living on the island who gather at local bars that play sports games, including American football. Belizeans actually love American football! What I don’t know is if they only play the big games at the sports bars. I’ll rely on one of our football buffs who live in Belize and frequent this forum to respond. But you could drop by several sports bars and ask. I’d suggest checking out Lola’s, near the Phoenix Hotel, and Carlo and Ernie’s Runway Bar, by the airport.
