 Why we love it: delicious margaritas, reasonably priced, fun vibe&amp;nbsp;  Rio is also located in downtown Boulder. It offers a similar sprawling mountain view and some of our favorite margaritas (there is even a 3 marg limit because they’re so strong!) They offer both 'on the rocks' and 'frozen' with a variety of flavors (Manberry, anyone?) Pair it with the complimentary chips and salsa and you have a match made in heaven! It's a really popular spot, so you will likely have to wait to find a table if you go during happy hour. They have a really fun vibe and we love that it’s open til 10pm!&amp;nbsp;
