As for tomorrow night's trek to Splash...
Since there will be a gathering at Barrymore's, I'm thinking the best plan of attack would be to meet at Barrymore's - if you won't already be there for the dinner at 8:00, and we shall subway en masse down to Splash.
Musical Mondays starts at 8:00 and continues until midnight upstairs, and then until 2:00am downstairs in the lounge.
If you will be meeting us at Splash later in the evening, the bar is located at 50 West 17th Street (between 5th and 6th Avenues, closer to 6th Ave.) You can take the 4/5/6/N/R to Union Square; the F/L to 14th St. @ 6th Ave.; the 1/9 to 18th @ 7th Ave,; or the 1/2/3/9 to 14th @ 7th Ave.
There is usually no cover charge, but sometimes one will kick in past 10:00 - usually just $5.00. Cokes run about $4.00, and rail drinks start at $6.00. There is NO drink minimum.
You do not have to stay the whole evening. It's just a block or two walk to the nearest subway, and if the A train runs Express from the 14th street stop - just two stops to Times Square.
There are video screens all over the place, so you will be surrounded by Barbara, Liza, Jennifer, Idina, Patti and many other throughout the evening. Bars and restaurants in NYC are non-smoking, but the noise levels can still cause a bit of ringing in the ears. *The decibel level in the downstairs lounge is at a more comfortable level. It truly is just a nice place to hang out and have fun. And people watch. *Splash can get warm sometimes, so dress accordingly. It's very casual - jeans and t-shirt are prefectly acceptable.
