I went here not knowing it had been on Diners, Drive-Ins and Dives, but I had heard that they had a taco tuesday and wanted to check it out. For those who walked in expecting it to be upscale (I saw an M5 out front), it is totally a dive bar. I had a couple coronas out on the "patio" out back (really some concrete and a chain link fence), and the wait staff made a special effort to bring the tacos out to us since they didn't usually serve out there (it was mostly smokers).
HOWEVER. The tacos were absolutely delicious. The vibe is totally laid back and every song that came on the sound system was awesome. The servers were friendly and helpful, and not overbearing. The beers are cheap and they had a good variety on tap. I will definitely be back to check out the rest of the menu (hence the 4 stars, so far). Quit being snobby about your dive bars people. Parkview is a total gem.
