When you are caught in stop and go (mostly stopped) traffic and getting hungrier by the minute, the only thing to do is turn off onto a side street and find an Irish pub.
Hamburger and French fries = comfort food to soothe the traffic-challenged soul. But, in Oaxaca??? Yes, McCarthy’s Irish Pub in Reforma! Probably wasn’t the best dining decision we have ever made. French fries were pretty good, but hamburgers left a lot to be desired. However, by the time we left, the traffic had thinned and it was smooth sailing home!

More US style sports bar than Irish pub in my opinion but I quite like the vibe in there and they serve Guinness!
Will stick to the Guinness, if there is a next time! 😉
