If you do the thing out of plexiglass you might want some real glass on the top....plexiglass will scratch to hell in a month.
I am also not sure if the plexi glass will have an effect on fish...I'm not a fish guy but I don't often see tanks made out of plexi-glass...maybe it leeches toxic stuff into the water.
One more thing....that fish tank has to be removable somehow....because you need to clean it or it's going to look disgusting.
I'd actually recommend shallow fish tanks across the top instead of in the thin one in front. In the front = near peoples legs, they don't see it anyway if they are sitting at the bar...and hard as hell to clean. In the top you just lift the glass up, and they see the fish all night. If you do in the top I think like 3 seperate fish tanks would be cooler...so all the fish don't migrate to one end, also you could put different types f fish in there without them eating eachother (seems any friend that had mixed fish had cannibalization issues). The big issue jere is keeping spilt beer from leaking into the tanks...fish+beer is probably not good.
Another thing about plexiglass or glass is transparent shit is a REAL pain to keep clean, especially if you got drunk people on semi-spinning chairs...I can imagine your going to have rubber marks on the glass every night from shoes. And fingerprints out the ass. I'd recommend frosted glass for all of it except the fish tank tops...then you could still do like a neon light or something behind it. My entertainment center has 2 fairly large glass windows in it, with lights behind them....they always look dirty.
I assume you already have "bar games", pool table, darts, foosball, card table etc....to me those are far more important then a fancy bar. A TV in the bar's vicinity is nice too, but I don't watch sports a whole lot.
Card games like Kings or asshole are good for mixed company, connections, circle of death are good if it's just the guys. Most of those games are best with 5+ people. 3-man and quarters require a larger table then a bar also. Chandeliers requires a stable table, no cheap shit.
If you want to go on the crazy side...I'd have a functional beer bong mount that looked like a giant IV..much better then kareoke mics heh.
Another thing you could do is make some sort of transparent container on the bar that held a large amount of liquid, expecially cool if it keeps it cold. You could have a "shot of the night" or some strong ass punch in it...and then a little tap on the side to dispense it.
Shots:
Kamakazi - vodka, triple sec, lime juice (I think equal portions)
Green apples - 99 Apples (1/4), green apple pucker (1/4), sweet and sour mix (1/2)
Or if you go the punch route:
2.5 gallons HI-C fruit punch, 1 liter of everclear I think it's roughly 2x as strong as domestic beer, and you can't taste the alcohol. Everclear is 190 proof. It's cool if you have hardwood, or lineoleum or something, but on carpet you will have issues.
Also I highly recommend a kegerator or something....buying beer in bottles is expensive...you can go high class and use some real glass, but that's high maintenance (cleaing lots of glasses per night) or plastic cups (throw them out, but they tip easier then a glass mug, and don't keep beer as cold).
Usually people end up with snack cravings, toaster oven, microwave, and deep fryer aren't bad things to have in the bar area. Usually we get some like eggrolls, fries, cheesesticks, jalopeno poppers, or something going. You can get away with ruffled potato chips, microwave popcorn, tortilla chips with shredded cheese in the microwave...chips + salsa...nuts...
It starts getting expensive when they raid the actual fridge. Microwave dinners are a lot more expensive then say an eggroll from sams club (20 for $8, they are good)....plus you don't go to get dinner the next night and find out you have no food.
If you are the "good times club" then making the other guys chip in for the food they eat should be acceptable, when you got random people it's impossible.
I'm known for getting real drunk and cooking up a bunch of real food on the grill at 4am, that used to get really expensive. Grilled porkchops was my specialty.
What other stupid gimmicks could you do? I dunno maybe one of those little basketball hoops with the like nerf ball...you could challenge someone and you both take a shot, whomever misses chugs thier beer.
My place isn't large enough for an official bar area.
