Are there any sports bars in Puerto Vallarta to watch Sunday football?
Lots of them. Where are you staying?
El Torito in old town can't be beat. Lots of TVs, cold beer, good food and a sports book
What part of town?
The OP has another post asking for spa recommendations in the Hotel Zone so is probably staying in that area.
Wings at Villa Del Palmar is just to the north of you. They do not take cash, credit card only. Open 12 pm to 1 am. They also include a 12.5% tip automatically on your bill, so if you tip additionally be sure to adjust your tip percentage.Edited: 12:25 pm, October 16, 2017
We sometimes watch football at NACHO DADDY'S. in old town not too far from El Torito's
Good food and reasonable prices.
