Love the cosmopolitan and have been to Holsteins a couple of times.  It has a fun and casual decor (hot pink cow in front) matched with a really nice looking bar.  \n\nSat at the bar both times.  The bartenders were friendly and suggestive without being too intrusive.  They have a great beer selection and will help recommend one if you want to try something new.  Although I usually like ordering specialty cocktails at places like this, I noticed that they had bubble-gum vodka (one of my favorites) so the bartender made me a  bubble-gum martini that was delicious! It was pink and girly...definitely what I was in the mood for. \n\nFor food I had the duck 'street tacos'. I love anything and everything with duck, but then add foie gras, and truffle cream and stuff it into a crispy tortilla? yuuummmm! \n\nAlso ordered the Lobster Mac-n-cheese. Its a perfect size portion (so you can eat it all and be guilt-free). I just happen to be a mac-n-cheese connoisseur, so I've had my share of cheesy noodles. This one is really good with the lobster and truffle cream, but not my favorite. However the dish comes with a mini lobster BLT that is so good I would definitely order it again. (You can only get this little mini blt with the mac, it's not a menu item on its own). \n\nHolsteins is a cool hang-out spot.  Not just an ordinary burger joint, they have really creative things on the menu that you wouldn't expect. Will definitely come back, there are still so many things I want to try!
