STEVEN TYLER made a pit stop at a Boston-area Olive Garden the other day . . . but it wasn't for some of that authentic Italian cuisine. He had to URINATE.
An employee says, quote, "He didn't order food, he came in to use the men's room. I saw his limo when I came in and it was really quiet. No one recognized him because of the age group of people in here."
After he went into the bathroom, word started going around about who he was, so there were people waiting when he came out. Another worker says, quote, "He was really cool and took photos."
On his way out he asked for breadsticks, so they gave him some. And even though they didn't charge him, he did NOT leave a tip.
