The popular Red Spot is a good place to go for a nice, informal meal at an inexpensive price.
The menu has a lot of stuff to choose from... From burgers and sandwiches, to pizzas, African chicken, Beef Stroganoff, Thai curries and Chinese fare...
Prices are very moderate and ambience is quite casual and informal (it is within the university grounds...) but the problem is that it's far from everywhere...
Located on the campus of MUST (Macau University of Science & Technology), between the airport and COTAI (not far from the Venetain)
Open daily, 10 am - 9 pm (closed on Sundays, during summer)
