Everybody's Irish on St Patrick's Day, even at Cozumel! Check out the pics from Cozumel Grill & Tequila Bar on St Patrick's parade day. For all of your downtown & Allentown events, Cozumel is a favorite watering hole. And, now that spring is just around the corner, Cozumel's famous patio is already starting to show signs of life. Take advantage of the break in the weather this week to enjoy a lunchtime or happy hour drink in the sunshine on the patio at Cozumel Grill & Tequila Bar.
