I goto McD's twice a year. Shamrock shake and McRib. This year I added a 3rd trip during the BOGO offer for the new Quarter Pounders.
Drive thru here offers two lanes to order that converge into one for pickup. Drivers beware. Many drivers leaving the DriveThru also U-turn into the parking area on the East side, so it's probably not a great place to park - and you take your life into your hands if you are trying to leave the Wal-mart via that passageway.
We found the new habanero QP to be fairly tasty, with a giant slice of tomato and the sauce was actually decent, with some spice to it. Not hot, but hotter than I expected from McD. I was gonna give them 3 stars for the fact that I was pleasantly sursprised.
Then, I remembered that my previous trip here they didn't have shamrock shakes. They were out. Like 3 days into the limited time promotion. Back to two stars.
