The best restaurants serving American food in Roebuck Stevenage East of England

I normally visit the drive-thru with mixed results but I do like the food when it's right and some of the king saver items are great. Staff often seem uninterested, miserable or just plain rude. And I've had whoppers with mayo or ketchup and missing most of the salad, and just lukewarm or cold burgers. This time, I wanted to use the delivery as there was an offer for two for £12.99, ordered at 5.39PM on a Thursday. Two and a half hours later, the order still wasn't on the way when I finally managed to speak with someone to cancel. I spoke with the 'restaurant' around just under 2 hours into waiting and they let me know they had no order details of mine and there was nothing they could do (despite my order changing to preparing here and there via the app). I then spoke with Uber Eats who said it wasn't on them and told me to contact Burger King instead. I eventually found another Uber Eats line to call or whatever is on the email and they said it'd only be another 5-10 minutes, despite this being the 4th or maybe 5th driving going to 'collect' my order. Barely an apology and no offer of a voucher or anything. Awful experience - it's on me for going back despite the staff and inconsistent food, but a joke, nonetheless. I'll stick to Mcdonald's and other establishments instead.
