Inconsistent service and food quality

Today I took a friend for lunch at Mugg and Bean in Kenilworth Centre. The last time I was there I left a great 5 star rating on Google Maps for the lovely service and the delicious salad and iced coffee shake, but today the service was not good. The waitress was not very sociable and didn't tend well to our table. We didn't receive plates for our meals until a few minutes after the meal arrived. Between two people we ordered three of the meals to share options:the chicken livers, spicy bbq chicken wings and onion rings. We had iced coffee shakes to drink. The iced coffee lacked flavour and was mostly a frothy mixture that had icy bits in it, very much watery and wasn't anything like the milkshake consistency as the iced coffee thick shake that I had ordered the previous occasion.

The presentation of the chicken livers were like that of pap, but only it was grey(looking almost like ****), with large slices of red onion peaking through the grainy mess. There was no sauce and it didn't resemble anything in the picture of the menu. I was apprehensive about trying the chicken livers but to my surprise, it tasted like some type of spicy patè. Not bad, but the presentation didn't have me or my friend want to finish even half of the dish we were sharing.

The spicy chicken wings weren't great either. Edible but it had a strange aftertaste. It didn't taste like bbg wings ought to taste. The dressing that it came with was some kind of blue cheese tasting sauce that had a greenish tint and it was way too sweet and it clashed with the odd taste of the spicy wings.

My friend had a really bad week and I wanted to treat her today just to feel better. She isn't someone that would complain about service and I would imagine that she wouldn't want to let me down by saying anything about the food, and neither did I want to put a damper on the afternoon by complaining about the food and service myself, so I preferred leaving this review about the poor service at M&B today.
