In general, none of the DLR restaurants are quite like 'Ohana (I assume you're talking about the coconut races and food fired grills), WCC (the antics), Sci Fi (the movie clips and car seating), or HDDR (the show). Many of the other venues at DLR are good, but they don't tend to have very many interactive activities.
Overall, I would also recommend Big Thunder Ranch BBQ; it's probably the closest restaurant in terms of atmosphere to the ones you listed that are at WDW. It has live music and a little stage show (nothing nearly as elaborate or campy as HDDR). Small children are encouraged to join the performers on the stage. However, they do not do any of the antics like they do at WCC.
Blue Bayou is DLR's signature restaurant, but it's much closer to San Angel Inn in terms of atmosphere. It's located inside the PotC building, so it's dark inside and you can watch the boats float by. While I like the food, I would not describe it as fun in the same sense as HDDR, 'Ohana, Sci Fi, or WCC.
I really like Ralph Brennan's and they have live music in the evenings (at least I think they do on most nights). Again, however, they remind me more of Raglan Road (minus the dancing) than any of the places you mentioned.
There isn't much seating, but you might want to check out Trader Sam's Enchanted Tiki Bar. It has some food, and an interesting atmosphere. It's a little like 'Ohana (not a lot, but does have some Polynesian flare). No games or coconut races, but still fun to see. You do have to go early because in the evening it becomes an adults only venue (over 21).
Otherwise, I do think the French Market might be a good choice. The Royal Street Bachelors perform and you can do a fair amount of people watching while you eat. Flo's V-8 Cafe might also be a good option because of all of the decor and you can watch Carsland (either the street or RSR, depending on where you sit).
