Two different smoothie meanings
The Juicer at level 60 makes the customer drink called Smoothie and sells it for 1,320 Coins. Gift smoothies from food stalls restore staff energy. They are not the same item, and buying Apple Smoothie for Hello Kitty does not unlock the Juicer.
What to buy as you level
Machines unlock by player level. The city store on the first floor sells the higher machines. Equipment through about level 15 is also in the town store. Dessert stations need their display on a counter. The three ice cream machines sit on the floor.
Drink machines can be upgraded. The second tier is a task, commonly after serving 100 of that drink. Prestige, the third tier, costs Diamonds and makes more drinks per cycle. The Coin price of one serving stays the same. The Juicer prestige figure recorded for that machine is 3,999 Diamonds. Quick Serve and Quick Stock are separate one-time effects at 199 Diamonds each.
| Stop | Level | Machine cost | Serving price |
|---|---|---|---|
| Americano Machine | 1 | 350 Coins, given in the tutorial | 98 |
| Cupcake Oven | 3 | 500 | 120 |
| Cappuccino Machine | 13 | 2,100 | 493 |
| Croissants Oven | 15 | 6,000 | 653 |
| Boba Tea Machine | 34 | 55,000 | 903 |
| Juicer | 60 | 150,000 | 1,320 |
| Blue Tea Machine | 68 | 200,000 | 1,530 |
Kuromi Cake Oven is the exception on this list. It costs 10,000 Coins, has no level lock once you can shop in the city, and its cake sells for 653 Coins. Buy it when you want that menu item, not because it is the next level reward.
How to choose the next machine
If two machines are already unlocked, compare Coin cost with serving price and whether you can staff the station. A cheaper machine that you can run now beats a later machine you cannot power. The full shop order, from Cupcake through Blue Tea, is on the equipment pages.
Player level caps at 70. Level-ups grant 20 Diamonds, and main tasks that say reach a level stop at 70. Serving customers is the XP path, and staff can keep serving while you are away from the counter.
