Boost Juice Bars

I called in Boost Juice Bars today to grab my free birthday boost having signed up to their loyalty card Vibe scheme on a trip to Sheffield in May.
Boost are an international smoothie-​bar company, which is rather big in Austrailia and expanding in The UK since opening its’ first store in The Trafford Centre in the late 2000’s. This store in particular is in the Manchester Arndale, and is a rather new store which replaces their store at Piccadilly Station and replaces Shakeaway in the Arndale.
Boost tend to have good quality, healthy drinks but still they seem to be rather expensive, with some «Regular» size drinks costing over £5.10, with an average price of around £4.80, which is actually how much I should have paid for my Regular Banana crush with extra banana and cinnamon.
The guy who served me seemed rather nice, and energetic in jumping from the till, to make my smoothie, he seemed to have passion and enjoyment for his job, which was refreshing to see (If I worked at Boost, I’d probably loose my enthusiasm after the first drink I make!), he seemed helpful to offer me suggestions to my drink, such as extra banana, to help get the most out of my free drink and of course wished me happy birthday. (If the drink wasn’t enough)
The drink tasted quite nice, with good flavors of banana and honey and cinnamon, and it did taste fresh, although it still wasn’t perfect, or probably the best choice on the menu, and definitely didn’t warrant the £4.80 price it should have been, and a better price would be a more favorable, but still generous £2.80. In my opinion, £4.80 still is too expensive.
This is quite a nice store, although it doesn’t have any seating in like Shakeaway did, it mainly acts as a grab-​and go smoothie bar, like all Boost’s other locations, but still it has a store you can actually walk in, compared to branches I have seen in Sheffield and The Trafford Centre.
The staff are great, the quality is good, the loyalty scheme is satisfactory but the prices are very unfavourable and far too expensive, making this the Hilton of the smoothie world, but still I feel I can give a generous 3 star.
