this analysis identifies "there" as an expletive (expl), "food" as a nominal subject (nsubj), "kitchen" as an oblique object (obl), and "in" as a case marker (case) -- there is also a dependency connecting "the" to "kitchen", but it is not shown. note that the copula "is" in this case is positioned as the root of the sentence, a fact that is contrary to how the copula is analyzed in the second example just above, where it is positioned as a dependent of the root.
