Don't get me wrong - I love Espresso Royale. I love their coffee, and I used to frequent the Espresso Royale back in Ann Arbor, MI when I lived there. I even like the other ERC's on campus. This one just always kind of falls short for me. I still come here sometimes due to its proximity to my workplace, but I frequently find the staff to be rude, kind of rushing you even though there's nobody else in line, rarely smiling, etc.
Furthermore, while I LOVE their coffee - very flavorful, but not overly strong or burnt-tasting like Starbucks - their pastries here are consistently awful. Frequently, they are stale, other times simply flavorless. Today, I was served a bagel so stale that it is difficult to chew. Disgusting. I also agree with the comment that the bathrooms are weird and awkward and frequently dirty.
Overall, not a bad place, but not a great one - the other locations are MUCH nicer.
