How many guests can one coffee cart serve in Lake Oswego?
A single barista generally serves 30 to 70 drinks per hour depending on the menu. Simple drip and cold brew service runs at the higher end, while a full espresso menu with milk alternatives and latte art runs slower.

Above that, most vendors in Lake Oswego will recommend a second barista or a longer service window so guests are not queuing.
What is the difference between a coffee cart, a coffee trailer, and a mobile coffee bar?
The terms overlap, but in practice a coffee cart is a compact setup that fits indoors and suits offices, lobbies, and receptions. A coffee trailer is a towed unit built for outdoor events, festivals, and larger guest counts, and it needs parking and access space. A mobile coffee bar or pop-up espresso bar usually means a table-based setup assembled on site. Most vendors serving Lake Oswego can advise which suits your venue once they know the space and guest count.
Do coffee cart vendors in Lake Oswego travel to my venue?
Yes. Mobile coffee carts are built to travel, and most vendors serving Lake Oswego cover the surrounding metro area. Travel beyond a vendor's standard radius may add a fee, which is worth confirming when you request a quote.
