My friend developed an online ordering app for busy bars called SpeedeTab.[1] Being able to order a drink and pay at the same time from a phone is very nice. When the drink is ready the phone gets a push notification. The bartender verifies the transaction number of the phone. Because they are doing credit card transactions in bulk they got a very decent discount and they passed that onto the bars and coffee shops like you mentioned with LevelUp. For restaurants, getting the transaction fees at around 1% is a big deal because that is a lot of the net profit. I haven't heard about LevelUp yet, lot has changed in the past 10 years, and I'm out of the loop now.
