This question already has an answer here:
Well we know that is is the correct form for singular and are is the correct form for plural, right?
As such "There is a great pizza place in Chicago" would be correct in prose or dialogue as would "No, actually there are many great pizza places in Chicago."
However, I hear and occasionally myself say, "If you go to Gino's, I'd stick to the one downtown, but there's several locations now."
So my question is: Is this tense mismatch an eccentricity of speech, or is there any basis for this contraction of there's in plural?
Are you hungry now?
Edit: My question specifically asks for an irregular usage concern. Of course I know what it's supposed to say.
