On the Border introduced their Summer frozen margarita flavors last week. it didn’t take long for me to go and check them out! I love their standard frozen flavors (regular, strawberry, sangria, and swirls). last Summer they had watermelon and I recall it being quite good. so I went for the mango this time, being that its the newest. I got it plain and then got it swirled with strawberry. both were highly recommendable! welcome, Summer!
