Hi Philip I dont know exactly what you have in mind but Nuts Huts on the Loboc river caught my eye its on page 271 of the lonely planet philipines guide and run by a Belgian couple
Yes, we saw Nuts Huts, when we took a little trip on the river, to see the waterfall. Also stopped on a raft, where some kids, were singing, dancing & playing ukelele's. Had our photos taken. They were really good...Didn't try the floating restaurants though.
