Order a few beers at Pedro's Sports Bar, and you shouldn't have a problem plugging in there.
There's an outlet on the right of the TV, and a table you could sit at.
The SSID for the router is "linksys" and it's a decent speed.
I always go to Pedro's when my internet fails me at home
It would also help to know where you are located at! If you're north of the bridge, Coco Loco's has wifi with the SSID of "Rancho Belize" and Linda won't mind at all if you use it. You can sit right at the bar, and she'll plug it in for ya!
Hope this helps!
