I'm going to keep this short and honest: RP Adler's is overpriced, cheaply decorated, poorly staffed, and populated by a fairly douchey crowd. The food is poor and drinks are mediocre. Bartenders are surly men aged 40+ with no employment options at a legit establishment and the waitstaff 30 and under hired for "looks" and nothing else. Ladies -- you're not that cute, trust me.
Cocktails are adequate at best. The food is poor -- just order one of their $9 burgers made from a pre-frozen patty you could buy at Copps for a quarter. On the whole, the place is a joke.
There are many other bars in west Madison. Even going to Chili's should provide you with a better experience. Stay away.
