Don't think Agua Marina Suites was renovated much, though it has reopened recently under "new ownership" and some work was done. It was only open a few months when it closed. The typical Belize story about who got the money and how much continues ...
I'm sure you'll have a great time.
If you'll search here using "restaurant" as your key word you'll turn up a bunch of stuff.
Among my faves are, at the upper end, Capricorn, Caliente and Blue Water Grill; at the middle range Jam-Bel Jerk, Papi's, Jade Garden, Sweet Basil; inexpensive Los Cocos, Ruby's (for breakfast), and the vendors at Central Park. But there are many other good places.
